Apollo Server v2.21.0 will fix this. I published alpha packages with version v2.21.0-alpha.0. I’d love some folks to try the alpha and let me know if it works for you! Both folks who actually use the upload feature and those who don’t! It’s currently in the release-2.21.0 branch, being tracked at https://github.com/apollographql/apollo-server/pull/4922

I’m going to close this as duplicate of #4865 but I’ll make sure to note that it might be slightly different than just a peer dep issue.
